近几十年来，环境问题、能源结构多样化的需求以及技术进步使得分布式发电（DG）在全球范围内增长。DG的主要和公认的好处之一是它能够推迟未来与需求相关的投资，为受监管的分销网络运营商（DNOs）提供潜在的显著节省和竞争优势。本文提出了一种考虑逐次淘汰法和多阶段规划的方法来量化DG带来的投资延迟。在这里，DNO可以清楚地识别受DG连接影响的每个所需加固及其实施时间表。对典型的英国配电网电路进行了评价。结果表明，DG的位置、尺寸、功率因数和调试时间等特性可以显著降低总体规划成本。每兆瓦连接DG的投资延迟也作为一个指标进行了研究，该指标可以帮助dno评估潜在连接点的吸引力以及量化DG产生的效益。
Environmental concerns, the need to diversify the energy mix, together with technology advances have made Distributed Generation (DG) increase worldwide over recent decades. One of the major and well-recognised benefits of DG is its ability to defer future demand-related investments, providing potentially significant savings and competitive advantage for regulated Distribution Network Operators (DNOs). In this paper an approach that consid- ers the successive elimination method and multistage plan- ning is proposed in order to quantify the investment defer- ral brought about by DG. Here, each required reinforce- ment and its implementation schedule affected by the con- nection of DG can be clearly identified by the DNO. A typical UK distribution network circuit is evaluated. Re- sults show that characteristics of DG such as location, size, power factor and the commissioning time can result in significant reductions of the total planning costs. The in- vestment deferral per MW of connected DG is also investi- gated as an index that could assist DNOs in evaluating the attractiveness of potential connection points as well as in quantifying the benefit produced by DG.
